Also adds MutatingScope::applySpecifiedTypes (filterBySpecifiedTypes without Scope::getType()) and the specifyTypesCallback slot on ExpressionResult consulted by getTruthyScope()/getFalseyScope(). The cycle collector is disabled in bin/phpstan - scopes deliberately never reference a storage directly, only the stack. Popping severs the stack->storage edge when an analysis ends, so retained scopes do not pin the whole result graph.

The old-world TypeSpecifier dispatcher answers nodes of converted handlers from the stored ExpressionResult (MutatingScope::specifyTypesOfNewWorldHandlerNode), processes synthetic nodes on demand (the 'foo' === $a::class rewrite builds synthetic Instanceof_ nodes), and falls back to specifyDefaultTypes when the result carries no callback - which is exactly what such handlers used to implement. Exercising the machinery surfaced two gaps in applySpecifiedTypes: - Expressions not tracked in the scope lost their sureNot narrowing ($var->name instanceof Identifier ? ... : ... stopped narrowing the else branch). The current type to intersect with or subtract from is now priced from the stored ExpressionResult (getCurrentTypesOfSpecifiedExpr) instead of Scope::getType(). - Only Yes-certainty holders hold the current type of an expression. A Maybe-certainty holder holds the when-defined type (falsy after an or-merge in nsrt/bug-pr-339.php), which the certainty-aware Scope::getType() never returned - narrowing against it produced NeverType and mis-fired conditional expression holders. AssignHandler's placeholder result for an assignment target now carries VariableHandler::createTypeCallback - every stored result for a converted handler's node type must answer type questions itself.

DefaultNarrowingHelper (recreated from the first rewrite attempt) carries the default boolean-context narrowing (one sureNot entry, no type ask, no nullsafe chain-walking) and createSubjectTypes(): ask the subject result's createTypesCallback, fall back to a single sure/sureNot entry for the subject node. No purity gates, no structural unwrapping. AssignHandler fans a type constraint out to the assigned variable and the assigned expression - nested assignments compose through the assigned expression's own result, which is what will delete unwrapAssign. CoalesceHandler delegates to its left side when the type rules the right side in or out, so ($e ?? null) instanceof Foo narrows $e. AssignHandler also wires specifyTypesCallback: the assigned variable narrows by the boolean outcome, plus the $arr[$key] inference after $key = array_key_first/array_key_last/array_search/array_find_key. The null-context inferences stay in the old-world specifyTypes() - result-based asks are always truthy or falsey. specifyTypesCallbacks no longer touch TypeSpecifier: VariableHandler uses DefaultNarrowingHelper, InstanceofHandler narrows its subject through createSubjectTypes(). TypeSpecifierTest's assign-in-instanceof expectations hold unchanged - the new channel reproduces create()'s emission exactly.

This deletes the founding pathology of the rewrite: BooleanAndHandler::resolveType's re-walk of the left operand on a throwaway storage, BOOLEAN_EXPRESSION_MAX_PROCESS_DEPTH and both flattened-chain code paths - deep chains compose through nested results. Child narrowing flows through DefaultNarrowingHelper::getChildSpecifiedTypes(): the child result's specifyTypesCallback first, bridged through the old-world dispatcher for unmigrated children (the dispatcher answers converted handlers from stored results, so the bridge terminates; it dies in 3.0). The ternary still rewrites itself as (cond && if) || (!cond && else) - the synthetic takes the on-demand path where its real subnodes answer from stored results. Lessons the conversion forced out of the engine: - A handler must never ask the scope about its own node mid-processing - no stored result exists yet, so the ask takes the on-demand path and recurses infinitely (CoalesceHandler's filterByFalseyValue($expr) for the right-side scope hung the suite). The equivalent narrowing is built directly from the left result instead. - Composite typeCallbacks evaluate later operands on their captured processing scopes. Re-filtering the asking scope loses the left side's side effects (by-ref writes, inline assignments); the child result's own point breaks synthetic compositions (min()'s $a < $b ? $a : $b reuses stored results of the real arg nodes, predating the synthetic's branch narrowing). The captured scope has both; native asks flavor it with doNotTreatPhpDocTypesAsCertain(). - ExpressionResult::getType()/getNativeType()/getTypeForScope() consult tracked expression holders before the typeCallback, mirroring the early return in MutatingScope::resolveType() - that is how the nullsafe handlers' ensured non-nullability of ($x ?? null) reaches type asks.

Rules hold FiberScopes and feed them straight into the old-world dispatcher (ImpossibleCheckTypeHelper passes the rule's scope to specifyTypesInCondition, phpstan-phpunit's assert extension builds a synthetic BooleanOr there), so resolveTypeOfNewWorldHandlerNode() and specifyTypesOfNewWorldHandlerNode() can run with $this being a FiberScope. They now call toMutatingScope() - identity on a plain scope, a state-preserving copy on a FiberScope - before invoking result callbacks and on-demand processing. Without the conversion the engine processes synthetic nodes on the rule-facing scope, whose type asks suspend: wasteful inside a rule fiber, fatal outside one ("Cannot suspend outside of a fiber").

By design those should only be synthetic nodes (built during analysis, no source position) - a real AST node left pending means a rule asked about its type but the producing handler never processed and stored it, so the ask falls back to on-demand processing (correct but wasteful, and on the asker's scope).

Measured slightly faster on NodeScopeResolverTest (less on-demand reprocessing). - The guard now tells a real AST node from a node built during analysis (rule-constructed comparisons, call_user_func/ArgumentsNormalizer rewrites) by membership in the parsed file (guardRealExprIds, collected once per file only when the flag is set), not by source line - synthetic nodes copy their origin's line, so the previous line check mis-flagged them as gaps. Rule-built synthetics legitimately resolve on demand. Off by default (zero cost). With it on, the only nsrt real-node gap was the IIFE, now fixed; the remaining src gaps (Closure/String_ in arg and key positions, comparison operands) are step-1 work, documented in NEW_WORLD.md.

A rule invoked at a scope's entry - e.g. UnusedConstructorParametersRule on InClassMethodNode - asks the types of expressions appearing later in the body; flushing at an earlier branch resolved those fibers on the asker's scope before natural traversal stored the results. The flush now happens only when the statement list is a scope body (FunctionLike, ClassLike, Namespace_); nested lists defer to it, and fibers are resumed when their expression stores its result. This is the documented design ("flush only at unit boundaries"). processClosureNode tracks the closure in processingExprIds while its body is processed, so a scope-boundary flush triggered inside the body (a nested closure or anonymous class) does not flush the fiber pending on the enclosing closure itself. processDroppedArgs handles arguments dropped by ArgumentsNormalizer - duplicate, unknown-named or extra arguments in an invalid call. The parameters check still asks their types to report the error, so they are processed (NoopNodeCallback) and stored even though processArgs iterates only the normalized argument list.

Such an ask resolves the type by re-processing the node out of order - the double-processing that makes a node analysed several times. Tracking is collected per file only when the diagnostic is enabled (cached as NodeScopeResolver::$guardNewWorld): $guardRealExprIds is every parsed-AST Expr, $guardProcessedExprIds is every Expr processExprNode has stored. MutatingScope::getType throws when a real, not-yet-processed node is asked. Rules ask through FiberScope (which suspends and is answered from the result), so this targets only the old-world MutatingScope asks. Off by default - one static bool read per getType when disabled, no measurable cost. The existing pending-fiber guard and the real-node set are reused, now static so MutatingScope can read them.

A lazy typeCallback cannot be used: getClosureType re-processes the closure body and closures are excluded from hasTrackedExpressionType(), so each getType() on the closure re-walks the body and re-asks the closure's own type before the cache is populated - unbounded re-entry. A closure whose ExpressionResult is not stored yet (its body asks its own type while a callable parameter is being derived from it), and a closure passed as a call argument (stored by NodeScopeResolver without an eager type), are resolved directly via ClosureTypeResolver in resolveTypeOfNewWorldHandlerNode - mirroring resolveCallableTypeForScope - never on demand. A self-by-ref closure is answered by getClosureType's existing depth guard. ExpressionResult gains eager ?Type type/nativeType; the accessors return them first and getTypeForScope honours a native-promoted scope. This was the last handler implementing TypeResolvingExprHandler, so the interface and its two instanceof forks (MutatingScope, TypeSpecifier) are deleted. --- .../ExprHandler/ArrowFunctionHandler.php | 34 +++++----- src/Analyser/ExprHandler/ClosureHandler.php | 34 +++++----- src/Analyser/ExprHandler/VariableHandler.php | 3 +- src/Analyser/ExpressionResult.php | 34 +++++++++- src/Analyser/ExpressionResultFactory.php | 2 + src/Analyser/ExpressionResultStorageStack.php | 5 +- src/Analyser/MutatingScope.php | 64 +++++++++---------- src/Analyser/NodeScopeResolver.php | 22 +++++-- src/Analyser/TypeResolvingExprHandler.php | 30 --------- src/Analyser/TypeSpecifier.php | 4 -- 10 files changed, 118 insertions(+), 114 deletions(-) delete mode 100644 src/Analyser/TypeResolvingExprHandler.php diff --git a/src/Analyser/ExprHandler/ArrowFunctionHandler.php b/src/Analyser/ExprHandler/ArrowFunctionHandler.php index da01eb8e39f..d550800e416 100644 --- a/src/Analyser/ExprHandler/ArrowFunctionHandler.php +++ b/src/Analyser/ExprHandler/ArrowFunctionHandler.php @@ -9,27 +9,25 @@ use PHPStan\Analyser\ExpressionResult; use PHPStan\Analyser\ExpressionResultFactory; use PHPStan\Analyser\ExpressionResultStorage; +use PHPStan\Analyser\ExprHandler; use PHPStan\Analyser\ExprHandler\Helper\ClosureTypeResolver; +use PHPStan\Analyser\ExprHandler\Helper\DefaultNarrowingHelper; use PHPStan\Analyser\MutatingScope; use PHPStan\Analyser\NodeScopeResolver; -use PHPStan\Analyser\Scope; -use PHPStan\Analyser\SpecifiedTypes; -use PHPStan\Analyser\TypeResolvingExprHandler; -use PHPStan\Analyser\TypeSpecifier; use PHPStan\Analyser\TypeSpecifierContext; use PHPStan\DependencyInjection\AutowiredService; -use PHPStan\Type\Type; /** - * @implements TypeResolvingExprHandler + * @implements ExprHandler */ #[AutowiredService] -final class ArrowFunctionHandler implements TypeResolvingExprHandler +final class ArrowFunctionHandler implements ExprHandler { public function __construct( private ClosureTypeResolver $closureTypeResolver, private ExpressionResultFactory $expressionResultFactory, + private DefaultNarrowingHelper $defaultNarrowingHelper, ) { } @@ -43,6 +41,15 @@ public function processExpr(NodeScopeResolver $nodeScopeResolver, Stmt $stmt, Ex { $result = $nodeScopeResolver->processArrowFunctionNode($stmt, $expr, $scope, $storage, $nodeCallback, null); + // A plain typeCallback recursing through getClosureType() would re-walk + // the body each getType() ask before the cache populates and hang; + // ExpressionResult excludes closures from its tracked-type early return. + // Compute the ClosureType once here and store it as an eager value.

A property declared with a default value, e.g. `public ?int $value = null`, is always initialized, so its existence does not depend on whether it was read earlier. That order-dependence broke narrowing through `??`: for `$a->value ?? $b->value` the coalesce only builds the "left is null" scope for its right side when the left is surely set. With isSet returning "maybe", that scope was skipped, so a conditional established earlier (here an is_null && is_null throw guaranteeing one side is non-null) never fired and the result stayed int|null instead of int.

Each subject now narrows through its own stored result's createTypesCallback, falling back to create() only for synthetic subjects.

This surfaces every result that did not explicitly decide how it propagates its type / narrowing. Resolve all 23 surfaced call sites: results that genuinely do not narrow get an empty specifyTypesCallback; results that precompute an eager type pass typeCallback: null. Eight results that previously fell back to Scope::getType() (Assign / AssignOp / implicit to-string / a few NodeScopeResolver results) get a MixedType typeCallback as a deliberate stopgap - the whole suite stays green, which shows their types are not yet covered;

But an audit of the functionMap shows it buys almost nothing: of 125 multi-variant functions, the by-ref structure differs across variants in exactly ONE (sscanf), keyed off argument count; variadic differs in 23, all "catch-all vs explicit arity", also count-keyed. So a variant's by-ref/variadic STRUCTURE never needs a type read - only the return type (already resolved downstream from the gathered args) and rare generic param types do. Drop the forward-reading slow path. The metadata acceptor base is the first variant, and the per-argument resolution (already used for generics) now also runs for multi-variant, selecting the acceptor from the args gathered SO FAR padded to the full count with mixed. The mixed pad keeps the argument count correct, so the by-ref/variadic variant stays stable (sscanf's by-ref $vars are defined again) while processed siblings resolve generic callable(T) params; the by-ref OUT writeback resolves the same way. Closures sort last and by-ref out-params follow the args that pin them, so determining siblings are always processed - no forward read. processArgs is now fully single-pass under PHPSTAN_GUARD_NW=1 across multi-variant overloads, generics, by-ref out-types, Closure::bind and the intrinsic-override functions.

That was wrong in two ways: - the merge demotes a by-ref/side-effect definition made in the right operand (e.g. $m from $this->match(..., $m) on the right of an &&) to maybe-defined, losing it; and - applying the whole &&/|| narrowing re-applies the LEFT operand's narrowing on top of a scope where the right operand reassigned the narrowed variable - e.g. ctype_digit($foo) re-applied to the int $foo after $foo = intval($foo) in `!ctype_digit($foo) || ($foo = intval($foo)) < 1`, giving int<48,57>|int<256,max> instead of int<1, max> (bug-9400). && is truthy (|| is falsey) only when the right operand was evaluated - on the left-truthy (left-falsey) scope - and is itself truthy (falsey). That is exactly $rightResult->getTruthyScope() ($rightResult->getFalseyScope()): it already carries the left operand's narrowing (baked in by processing the right side on the left-narrowed scope) and the right's by-ref definitions, and does not re-narrow a reassigned variable. Pass it as truthyScopeOverride/falseyScopeOverride on ExpressionResult; only BooleanAnd and BooleanOr need it, as the only handlers that merge operand scopes. The narrowing exposed to parents still comes from specifyTypesCallback, so dropping its scope parameter later is unaffected. --- .../ExprHandler/BooleanAndHandler.php | 6 ++++ src/Analyser/ExprHandler/BooleanOrHandler.php | 6 ++++ src/Analyser/ExpressionResult.php | 18 +++++++++++ src/Analyser/ExpressionResultFactory.php | 2 ++ ...ditional-expr-narrowing-second-operand.php | 31 +++++++++++++++++++ 5 files changed, 63 insertions(+) create mode 100644 tests/PHPStan/Analyser/nsrt/conditional-expr-narrowing-second-operand.php diff --git a/src/Analyser/ExprHandler/BooleanAndHandler.php b/src/Analyser/ExprHandler/BooleanAndHandler.php index 50775774d30..218bc381b8b 100644 --- a/src/Analyser/ExprHandler/BooleanAndHandler.php +++ b/src/Analyser/ExprHandler/BooleanAndHandler.php @@ -95,6 +95,12 @@ public function processExpr(NodeScopeResolver $nodeScopeResolver, Stmt $stmt, Ex isAlwaysTerminating: $leftResult->isAlwaysTerminating(), throwPoints: array_merge($leftResult->getThrowPoints(), $rightResult->getThrowPoints()), impurePoints: array_merge($leftResult->getImpurePoints(), $rightResult->getImpurePoints()), + // && is truthy only when the right side was evaluated (on the left-truthy + // scope) and is itself truthy - that is exactly the right operand's truthy + // scope: it carries the left narrowing and the right's by-ref/side-effect + // definitions, and does not re-apply the left narrowing over a variable the + // right operand reassigned (bug-9400). + truthyScopeOverride: $rightResult->getTruthyScope(), typeCallback: static function (bool $nativeTypesPromoted) use ($leftResult, $rightResult): Type { $leftBooleanType = ($nativeTypesPromoted ? $leftResult->getNativeType() : $leftResult->getType())->toBoolean(); if ($leftBooleanType->isFalse()->yes()) { diff --git a/src/Analyser/ExprHandler/BooleanOrHandler.php b/src/Analyser/ExprHandler/BooleanOrHandler.php index 3e8c3d75c55..2c501b4b6ae 100644 --- a/src/Analyser/ExprHandler/BooleanOrHandler.php +++ b/src/Analyser/ExprHandler/BooleanOrHandler.php @@ -149,6 +149,12 @@ public function processExpr(NodeScopeResolver $nodeScopeResolver, Stmt $stmt, Ex isAlwaysTerminating: $leftResult->isAlwaysTerminating(), throwPoints: array_merge($leftResult->getThrowPoints(), $rightResult->getThrowPoints()), impurePoints: array_merge($leftResult->getImpurePoints(), $rightResult->getImpurePoints()), + // || is falsey only when the right side was evaluated (on the left-falsey + // scope) and is itself falsey - that is exactly the right operand's falsey + // scope: it carries the left narrowing and the right's by-ref/side-effect + // definitions, and does not re-apply the left narrowing over a variable the + // right operand reassigned (bug-9400). + falseyScopeOverride: $rightResult->getFalseyScope(), typeCallback: static function (bool $nativeTypesPromoted) use ($leftResult, $rightResult): Type { $leftBooleanType = ($nativeTypesPromoted ? $leftResult->getNativeType() : $leftResult->getType())->toBoolean(); if ($leftBooleanType->isTrue()->yes()) { diff --git a/src/Analyser/ExpressionResult.php b/src/Analyser/ExpressionResult.php index 5f5bbeb70a0..d5be16d74e8 100644 --- a/src/Analyser/ExpressionResult.php +++ b/src/Analyser/ExpressionResult.php @@ -50,6 +50,8 @@ public function __construct( callable $specifyTypesCallback, private bool $containsNullsafe = false, private ?IssetabilityDescriptor $issetabilityDescriptor = null, + private ?MutatingScope $truthyScopeOverride = null, + private ?MutatingScope $falseyScopeOverride = null, ?callable $createTypesCallback = null, private ?Type $type = null, private ?Type $nativeType = null, @@ -141,6 +143,16 @@ public function getTruthyScope(): MutatingScope return $this->truthyScope; } + // && is truthy only when the right operand was evaluated (on the left-truthy + // scope) and is itself truthy - that is exactly $rightResult->getTruthyScope(), + // which the handler passes as $truthyScopeOverride.
